I didn't know pdoxdos could handle a multi-line query where each line is doing something completely
different.

row1 an insert
row2 a changeto
row3 a check

using different columns.

I went through a few variations and did find occasional wrong results in the answer table, but
inserted and changed 
seemed ok.

I'm not going to try to emulate this behaviour, but am curious. Have you seen use of this concept
in the wild?
